Hot Water Systems in Garran
The 2605 postcode, covering Garran, Curtin and Hughes and surrounding areas, is home to around 4,709 households. With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Garran and the 2605 area, 355 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Garran's climate delivering an average of 4.8 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Garran
Across Garran, more homeowners and businesses are rethinking their hot water system as power prices climb and old gas units wear out. With an average household size of around 2.6 people and more than 4,400 dwellings in the 2605 postcode, reliable, energy efficient hot water is a big deal. Many homes are owned outright or with a mortgage, so upgrading from ageing gas or electric hot water to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical next step.
Garran’s climate is ideal for efficient hot water. The local solar exposure averages about 17.2 MJ/m² per day over the year, which works out to roughly 4.8 kWh of usable solar energy per square metre per day. That strong sunlight supports both rooftop solar and a well-designed solar hot water heating system, and it also helps heat pump hot water systems run more efficiently than in cloudier, colder regions. With median household incomes above the national average, many families here are looking for long-term savings and lower emissions rather than just the cheapest upfront hot water system price.
In 2605, separate houses dominate, with plenty of three‑ and four‑bedroom homes. That means solid hot water demand for showers, dishwashers and laundries. Efficient hot water systems like Rheem heat pump hot water units, Sanden heat pump models and solar brands such as Solahart or Rinnai solar hot water are increasingly common choices for households wanting the most efficient hot water system they can get. When you compare heat pump vs solar hot water, both can dramatically cut running costs compared with older electric hot water vs gas hot water systems, especially if you already have rooftop solar.
Average savings will vary by family size and tariffs, but typical annual bill reductions in Garran look like this:
• Old electric to heat pump hot water system: save roughly $400–$900 per year. • Gas storage to heat pump hot water: save roughly $300–$700 per year. • Gas storage to solar hot water system: save roughly $250–$650 per year. • Old electric to modern electric hot water installation with solar diversion: save roughly $250–$600 per year.
There have already been 355 efficient hot water installations in the Garran postcode, covering both heat pump hot water installation and solar hot water installation. Install numbers built steadily through the 2000s, peaking around 2009–2011 when incentives were strong, with 48 installs in 2009 and 40 in 2010 alone. While yearly numbers have eased since then, recent installs in 2024 and 2025 show ongoing interest in electrification, lower running costs and moving away from gas. Each new energy efficient hot water system helps cut local demand for gas and shrinks household carbon footprints.
When it comes to hot water rebate ACT programs, Garran residents can usually tap into a mix of federal and territory support. The national Small‑scale Technology Certificates (STCs) scheme effectively provides an upfront discount on eligible systems like a heat pump hot water system, rheem solar hot water or chromagen solar hot water, lowering the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, ACT hot water rebate options for heat pumps and efficient electric hot water system rebate schemes can further trim the hot water system price / cost, sometimes cutting the effective cost by a substantial percentage.
That means replacing an old gas or electric unit with a high‑efficiency heat pump or solar hot water vs electric hot water can often pay for itself in just a few years, especially if you run it on off‑peak tariffs or use timers and solar diversion. With good planning, your hot water ACT upgrade can save hundreds of dollars a year while keeping showers comfortable through Canberra’s cold winters. And if you ever need hot water repair or solar hot water repair, it pays to use technicians who know these newer systems inside out, including solar hot water tank replacement when older tanks finally give up.
If you live in Garran and your current unit is noisy, rusty or more than 10–12 years old, it is worth checking whether a hot water upgrade could work for you.
